IMPROVEMENT IN SHEET-METAL ROOFING.

Specification forming part of Letters Patent No. 140,582, dated July 8,1873; application filed November 26, 1872.

To all whom it may concern:

Be it known that I, GEORGE F. LEONARD, of Newport, in the county ofOrleans and State of Vermont, have invented certain Improvements inRoofing, of which the following is a specification This invention isapplicable chiefly to metal and slate roofs; and relates to theconstruction and mode of attachment to the sheathing of the fastenings,by which pieces of slate and sheets of metal are secured in position.The nature of the said invention consists in the features ofconstruction hereinafter described, by which the fastenings areprotected from moisture where they are nailed to the sheathin g. Saidinvention also relates, in part, to the. features of constructionhereinafter described, by which the joints between the metal plates,when metal plates or sheets are used, are protected from liability toleak, as hereinafter more fully set forth.

Figure 1 is a plan view, showing the con struction of apiece or sectionof metal roofing and its fastenings, made according to my invention.Fig. 2 is a vertical section of the same on a line parallel to the upperand lower edges of the roof. Fig. 3 is a vertical section through theroof on a line transverse to the plane of Fig. 2. Fig. 4 is a piece orsection of slate-roofing constructed according to my invention. Fig. 5is a vertical section of the same on a plane at right angles to theupper and lower edges of the roof.

AAare the strips of metal by means of which the main portions of theroof are secured to the sheathing B, on which it is laid. O is a cap,which is placed upon the upper edge of the roof, and which is made tofit upon the upper ends of the strips A A and the upper ends of themetal or slate which forms the body of the roof at that point. D D arestrips of sheet metal which, in the construction represented in Figs. 1,2, and 3, form the principal portion of the roof. The strips of metal AA may be of sheet-zinc or other suitable material, and are bent into theform, or substantially the form, shown in the drawings, and particularlyrepresented in Fig. 2, so that the fastening between two strips of theroofing is made of a single piece of metal bent over at the top, asshown, so as to form a double descending edge or rib, a, descendingoutwardly from the joint both on its upper and under sides, so as todeliver the water which may fall upon it on the roofing D and away fromthe joint, and thus prevent the water from running down upon the partsbb, which are secured to the sheathing by means of nails driven throughthe holes 0 0, shown in Figs. 1 and 4. The strips of metal D D areturned partly upward at their edges, as shown in Fig. 2, so as to shedthe water away from their edges and prevent its overflowing them, so asto fall upon those portions of the strips A A which are secured to theroof, and thus prevent any portion of the water from coming in contactwith the nails which hold the strips A A to the roof; and to furtherassure the realization of this result, I propose to cap the edges of thesheets D D with strips of tarred paper, d d, as shown in Fig. 2, or someother equivalent substance, said strips d at being turned over the edgesof the sheets D D, as shown. The sheets D D may be of zinc or othersuitable metal, and may extend from the top to the bottom of the roof.

In the use of slate as a roofing-material the construction has to besomewhat modified. The strips A A, in this case, have raised portionsformed therein to receive the cross-strips E E, which are so turned inthe fold as to lap over the upper edge of the slates F F, over whichthey are placed, as shown, and thus prevent the water from getting'underthe up per edge of the slates. The strips E E are, like the strips A A,made of a single piece of metal each, and fastened to the sheathing B bymeans of nails driven through holes in the edges, in a similar manner tothat already described with reference to the strips A A, the principaldifference between them and the strips A A being in the form given tothe exposed portions, to adapt them to shed the rain over onto the slatebelow, as shown in Fig. 5. One of the strips E E is placed between theupper and lower edges of each two pieces of slate, as shown in Figs. 4and 5.

I claim as my invention- 1. The strips A A, formed as described, withthe exposed edges projecting downwardly over the main body of theroofing, and the edges where they are secured to the sheathing beingextended under the main body of the roofing, as hereinbefore set forth.

2. The combination of the strips A A, constructed as hereinbeforedescribed, with the sheets D D turned upward at the edges, which areoverlapped by the strips A A, as hereinbefore set forth.

3. The combination of the strips A A and D D, and the sheets of tarre'dpaper or other packing d d, as hereinbefore set forth.

4. The combination of the strips A A and E E, constructed ashereinbefore set forth.

5. The combination of the strips A A and E E, and the slates F F,substantially as hereinbefore set forth.
